You don't want to show too much info usually.
But the operator needs to know what the sequence is doing.
And if it fails it needs to show him why. It's advisable to have a service page where you can see more details including I/O for troubleshooting, because eventually someone has to check a sensor or do something and they have to know which one it is.

Have timeout alarms so that when something takes too long the operator gets an alarm.

And then of course regular alarms on objects like motors, valves etc and their feedback signals.

You can also have alarms on weight changes, for instance to indicate that when something is filling up but there is no weight change.
